Alternative names

Wikilambda is just a project name. One of the first tasks of the projects will be to come up with the communities with a name for the project and that is available as a domain name. Some options include Wikifunction, Wikicode, Wikialgorithm, but I am sure the community will have even better ideas.

Related projects/proposals

The following projects would be most affected by Wikilambda, but all Wikimedia Projects will be able to call functions in Wikilambda.

• Wikidata - suggested to store abstract Content in Wikidata next to the item pages
• Wikipedia - suggested to allow to display Content from Wikidata for missing articles

There are numerous proposals that cover aspects of Wikilambda and that have been made over the years (going back to 2001). In this proposal we aim to extract the common goals and learn from the other proposals:

• Global templates - a proposal with some overlapping goals
• WikiAI - a repository for ML models
• Wikitemplates - similar to the Global templates proposal above
• WikiDerivations
• Wikilanguage - linguist knowledge needs to be recorded in Wikilambda beyond Wiktionary
• Girgit - may be developed in Wikilambda
• WikiSandy - index Wikipedia content semantically
• Wikimath - a wiki that can do math
• DRMF - capture mathemtical formulas
• Wikimedia Pi Abacus
• WikiProves
• WikiTeched - providing an IDE for developing etc.
• Global-Wiki - the parts regarding global templates and modules
• WikiApps - provide access to functions and algorithms
• EncycloPDia - computational knowledge engine
• WikiCalculator - implementable in Wikilambda
• Konsciajxo - seems almost the same idea, but goes well beyond that
• Wikilinguistica - information about syntax and grammar etc.
• Wikidioma - information about agreement and declinations etc.
• WikiCode - pretty much the same idea
• Wikibot - give access to content in Wikipedia
• Wikipedia Virtual Mind - could be implemented with Wikilambda

Domain names

Depends on the name.
